The Celtic Goddess - Danu

Among the ancient celtics Danu was regarded as the “Mother Goddess.” .
Danu is the “divine waters” falling from heaven and nurturing the sacred oak from whose acorns their children sprang. The waters of Danu went on to create the great Celtic sacred river the Danube.

The Thames, which flows through London, still bears its Celtic name, from Tamesis, the dark river, which is the same name as Tamesa, a tributary of the Ganges.
Danu in Sanskrit also means “divine waters” and “moisture.”
